Homeland Security is having a shot gun, rifle, and a good pistol, in your home with the skill and will to use it rationally. The Department of Homeland Security is nothing but a high position jobs for friends program IMO. It wasn't needed and it has made a mess of things.
I thought it was a bad idea at the time and now it's become pretty clear that my concerns were warranted. When has another layer of bureaucracy ever stopped a terrorist?
